A touch screen overlay is a device that allows for the interaction with a liquid crystal display (LCD) by sensing the first input signal when a user touches the screen. These overlays replace traditional mechanical buttons with a dynamic tactile feedback system, enhancing user interaction. Touch screen panels are widely used in various industries, offering a seamless and intuitive human-computer interaction experience.

One of the most popular technologies for touch screens is the capacitive touch screen, known for its accuracy and durability. These touch screen overlays are used in healthcare, heavy industry, ATMs, and museum displays, providing a robust solution for environments requiring frequent interaction and high reliability.

Interactive touch screen overlays can be integrated with LCD displays, offering vivid audio and visual effects. This technology is highly effective in improving user engagement, making it ideal for applications where ease of use and durability are essential.
